StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 28 April 2026; the live site may have changed since.

Quackr is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on April 28, 2026. The site is hosted on Firebase App Hosting and served through Cloudflare. The crawl picked up 24 technologies on this site, covering advertising, business email, hosting, and package cdn. The stack includes Angular, Tailwind CSS, and Brave Rewards.

For context, it's running a stack combination we've seen on no other launch.
